At DUOTONE we use a Medium Constant Curve for our masts (our bend percentages range between 61-63 bottom and 75-77 top depending on model and length). As this curve sits right in the middle within Constant Curve masts it offers the biggest compatibility of any bend curve. This makes our masts and sails the most compatible on the market.
